What is the difference between dominant and ressesive trait
Answers
Answer:
When an allele is dominant, the characteristic it is connected to will be expressed in an individual. When an allele is recessive, the characteristic it is connected to is less likely to be expressed. Recessive traits only manifest when both alleles are recessive in an individual.
Explanation:
Dominant means that one of the versions trumps the other. In our example here, brown is dominant over blue so you end up with brown eyes.
The way people write out dominant and recessive traits is the dominant one gets a capital letter and the recessive one a lower case letter. So for eye color, brown is B and blue is b.

Answer:
The best description of the likely impact of an invasive plant species on a warm ecosystem is:
The invasive plant species take over resources used by native plant species. Some plant species decrease in population, affecting the food source for consumers in the ecosystem.
Invasive plant species have the ability to outcompete native plant species for resources such as sunlight, water, and nutrients. This can lead to a decrease in the population of native plant species as they are unable to access sufficient resources to thrive. As a result, the food source for consumers in the ecosystem may be affected, leading to potential changes in the population dynamics of the consumer species.

Answers
Answer:
They both had a tail as an embryo.
Their arm and leg structure is similar but may have a different function.
Explanation:
They both had a tail as an embryo.
Vestigial structures are those body parts that have lost or reduced their original function during the evolution of a species. These vestigial structures might be found in many animals, including human beings. Vestigial structures were plenty functional for common ancestors. But with evolution, they degenerated, stunted, and became rudimentary for some of the new species.
During the first 4 months of embryogenesis, all mammals have a tail at some point in their development. Dogs develop this structure and keep it during their whole lives, but humans lose it with time during embryogenesis. The tail disappears, and its forming vertebras get fussed with each other composing the coccyx, which represents a vestigial structure. This tailbone is the remnant of a missing tail.
In many animals, the function of the tail is to stabilize, equilibrate and mobilize. But in humans, the coccyx, located at the end of the vertebral column, has lost this original function.
Their arm and leg structure is similar but may have a different function.
The fact that whales, humans, and dogs all have the same bones in the same order, but they matured differently in later embryological development, is an example of homologous characters.
Homologous characters have the same fundamental structures. They also share the same relations with adjacent structures, and they have the same embryological development.
These structures might show variations between organisms exhibiting them, according to their function and to the environment in which the organism lives.
These homologous characters are common in organisms related and that share a common ancestor.
They both had a tail as an embryo.

In 4 or more complete sentences, describe the process of protein synthesis and explain how transcription and translation creates protein
Answers
Protein synthesis occurs in the cell and is divided into 2 stages, namely transcription and translation. The process of transcription occurs in the cell nucleus by copying the genetic code in DNA and forming mRNA strands which are duplicates of DNA.
The RNA strands that are formed will come out of the cell nucleus and then undergo a translation process that occurs in the cytoplasm. With the help of ribosomes, the amino acids will line up according to the sequence of the genetic code in the mRNA to form polypeptide chains that make up the protein structure.
What is protein synthesis?
Protein synthesis is the formation of proteins in the human body and occurs in the smallest units, namely cells. Protein synthesis is divided into 2 stages, in the following order:
1. Transcription
Transcription is the process of copying the genetic code or DNA that occurs in the cell nucleus or nucleus. The process of copying the genetic code is carried out by unbinding the DNA with the help of RNA polymerase, then forming a copy of the genetic code that is complementary to the sequence of hydrogen bases in the DNA. The process of transcription produces a strand of genetic code called mRNA or RNAd.2. Translation
Translation is the process of translating the genetic code contained in the mRNA and occurs in the cytoplasm. With the help of the ribosome, the mRNA will be translated and the amino acids will move towards the ribosome. Amino acids will form a sequence that is complementary to the mRNA so that a polypeptide strand that makes up the protein molecule is formed.Learn more about Protein synthesis at https://brainly.com/question/15404950
#SPJ1
1. Transcription:
Transcription is the first step in protein synthesis and takes place in the nucleus of eukaryotic cells or in the cytoplasm of prokaryotic cells. It involves the conversion of genetic information from DNA into a complementary RNA molecule. Here's how it works:
a. DNA unwinding: An enzyme called RNA polymerase binds to a specific region of the DNA molecule known as the promoter. The DNA molecule unwinds at this site.
b. Complementary RNA synthesis: RNA polymerase reads the DNA template strand and synthesizes a complementary RNA molecule, using adenine (A), cytosine (C), guanine (G), and uracil (U) as the RNA bases, instead of thymine (T). This newly formed RNA molecule is called messenger RNA (mRNA).
2. Translation:
Translation is the second step in protein synthesis and occurs in the cytoplasm, specifically at the ribosomes. It involves the conversion of the mRNA molecule into a functional protein. Here's how it works:
a. Initiation: The ribosome attaches to the mRNA molecule at a specific start codon (usually AUG), signaling the beginning of translation.
b. Elongation: Transfer RNA (tRNA) molecules bring amino acids to the ribosome, guided by the mRNA codons. These tRNA molecules have anticodons that complement the mRNA codons.
c. Peptide bond formation: As the ribosome moves along the mRNA molecule, it catalyzes the formation of peptide bonds between the amino acids carried by tRNA molecules. This forms a growing polypeptide chain.
d. Termination: Translation continues until a stop codon (UAA, UAG, or UGA) is encountered on the mRNA. At this point, a release factor binds to the ribosome, leading to the release of the completed polypeptide chain.
In summary, protein synthesis begins with transcription, where DNA is transcribed into mRNA. Then, during translation, the mRNA is decoded by ribosomes, and amino acids are linked together to form a polypeptide chain, which eventually folds into a functional protein. This intricate process ensures that the genetic information encoded in DNA is faithfully converted into the proteins that carry out essential functions within cells and organisms.

Answer:
Negative physical impact on marine life, chemical impact on the water, and transport of native species.
Explanation:
Negative physical impact on marine life:
Plastic can be dangerous to creatures living in the ocean. Marine animals can fatally swallow plastic, become entangled in it, and even become physically impaired for the rest of their life.
Chemical impact on the water:
Plastics carry chemicals such as PCBs and DDT that can invade the water and cause harm to marine ecosystems.
Transport of native species:
Plastic can carry organisms from one part of the ocean to a relatively remote area. By introducing new organisms to an ecosystem, the flow can be disrupted and result in major consequences.

1. What is an ecosystem?
2. What are some examples of nonliving things in an ecosystem?
3. What are some factors that could affect the number of organisms in an ecosystem?
4. Why might organisms interact in an ecosystem?
5. Would you expect to find the same kinds of interactions between organisms in very different ecosystems? Why or why not?
6. Why is it important to understand feeding relationships in an ecosystem?
Answers
Examples of nonliving things in an ecosystem include sunlight, water, air, rocks, soil, and minerals.
Factors that could affect the number of organisms in an ecosystem include the availability of food and water, temperature, weather conditions, availability of shelter or habitats, the presence of predators and disease, and human activities such as deforestation or pollution.
Organisms interact in an ecosystem to obtain resources such as food, water, shelter, and mates, and to avoid being eaten by predators or infected by diseases. Some organisms also form mutualistic relationships, where both parties benefit from the interaction.
Different ecosystems can have different organisms and interactions based on the unique features of each ecosystem, such as climate, geography, and available resources.
Understanding feeding relationships in an ecosystem is important because it helps us understand the flow of energy and nutrients through the ecosystem. This knowledge can inform conservation efforts and help us manage and protect ecosystems for the benefit of all living organisms, including humans.
Answer:
1. An ecosystem is a system of interactions between living and nonliving things in a particular environment.
2. Some examples of nonliving things in an ecosystem include sunlight, soil, rocks, air, water, and temperature.
3. Factors that could affect the number of organisms in an ecosystem include availability of resources, predation, competition, and environmental changes.
4. Organisms interact in an ecosystem in order to find food, to find mates, to escape predators, and to compete for resources.
5. No, you would not expect to find the same kinds of interactions between organisms in very different ecosystems due to differences in biotic and abiotic factors.
6. It is important to understand feeding relationships in an ecosystem because understanding these relationships gives us insight into the stability, dynamics, and functioning of the overall ecosystem. It can also provide an understanding of how the ecosystem may respond to environmental changes.
